<p class="MsoNormal">I would recommend getting a<a href="https://www.thorlabs.com/thorproduct.cfm?partnumber=WPMH05M-488"> half-wave plate</a> and a <a href="https://www.thorlabs.com/thorproduct.cfm?partnumber=PBS101">polarizing beamsplitter cube</a>. This
is not cheap but the half-wave plate allows you to turn the polarization and to specify how much power you want in each arm. You can put (almost) all power in one arm or do a precise 50/50 illumination.<o:p></o:p></p>

<p class="MsoNormal">Hi,<br>
Simple question: is there a 50/50 beam splitter from Thorlabs someone could suggest for the dual illumination configuration? I've found the BSW10 plate beamsplitter. If there is an alternative method, please let me know.
<br>
Thanks,<br>
Oscar<br>
